CAS command question

[Alberto Candel]

Most likely my comment doesn't add anything new (compare DrD reference to TI's left) but left works on lists as:

Code:

left({1,2,3,4,5},3)={1,2,3}

This use is not documented (not on the HP Prime "help" or on the user manual. (I suppose that inequalities like x+y<1 are stored as lists {1,x+y} ?)

Also, there are two "right" commands: RIGHT() and right(). Cannot tell the difference.
